    The results turned out to be the way I predicted them to be. 3. T3 and T4 would be missing in the animal’s blood. 4. I would expect to see a decrease in hormone levels since the hypophysectomized animal cannot secret ay TSH. Part 2: 5. The normal rat’s BMR increased. 6. The thyroidectomized rat’s BMR increased. However‚ in comparision to the normal rat‚ the thyroidextomized rat’s BMR was lower than the normal rat (meaning the normal rat still had a larger BMR). The dose of thyroxine

    relative permeability of the membrane to Na+ and K+ in a resting neuron. Membrane permeability to Na+ is very low because there are only a few Na+ leak channels. The membrane is more permeable to K+ because of the higher number of K+ leak channels. 5. Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. The resting membrane potential depends on the intracellular and extracellular concentrations of the Na+ and K+ ions. Conductance would change the concentration

If one diffuses at a higher rate‚ the permeability changes. 5. Discuss how a change in Na+ or K+ conductance would affect the resting membrane potential. A increase in potassium will cause a more negative resting potential. ACTIVITY 2: RECEPTOR POTENTIAL 1. Sensory neurons have a resting potential based
